The Ecore ODA Driver is a proposed component of the [[DTP Incubator]] project. It will provide the ability to query Ecore models using [http://www.eclipse.org/modeling/mdt/?project=ocl OCL] by implementing the [[Use Case - Create a Custom ODA Data Source| Open Data Access (ODA)]] API. The restriction to use OCL (text-based) queries is based on the design of the ODA API. [http://www.eclipse.org/modeling/emf/?project=query#query EMF Queries] may be supported at runtime in the future.

Initial code has been committed (see [[#CVS|CVS]], below) but the code is not yet complete. While most of the driver itself is in place the UI requires some finish work.

Initial code has been committed (see [[Ecore ODA Driver#CVS|CVS]] on the [[Ecore ODA Driver]] page) and is basically functional. The UI, in particular, requires some finish work.

It is hoped that a useful release will be complete in time for [[Ganymede]].

The Ecore ODA Driver is only available from [[#CVS|CVS]]. After checking the code out a number of dependencies may be un-met in your workspace such as: [[Connectivity|Datatools Connectivity]], [http://www.eclipse.org/modeling/emft/?project=search#search EMF Search], [http://www.eclipse.org/modeling/emf/?project=transaction#transaction EMF Transaction], and [http://www.eclipse.org/modeling/emf/?project=query#query EMF Query].

Use of the Ecore ODA Driver is covered [[Ecore ODA Driver|here]].

Once the code compiles correctly, you can run the BIRT Report Designer and create a new report. When adding a Data Source a new type will display <tt>Ecore ODA Data Source</tt>. Selecting this Data Source and giving it a name will allow you to enter a Data Set. This is, however, the end of the line. As explained in [[#Status|Status]], above, the code is not yet complete. Column selection has not been implemented and the code currently in CVS does not correctly persist preferences.

The plug-ins are available from the [http://www.eclipse.org/datatools/downloads.php Eclipse Data Tools Platform (DTP) Project Downloads] page in the DTP Incubating Component - ODA Ecore section towards the bottom of the page.

Introduction

The Ecore ODA Driver is a proposed component of the DTP Incubator project. It provides the ability to query Ecore models using OCL by implementing the Open Data Access (ODA) API. The restriction to use OCL (text-based) queries is based on the design of the ODA API. EMF Queries may be supported at runtime in the future.

Status

Initial code has been committed (see CVS on the Ecore ODA Driver page) and is basically functional. The UI, in particular, requires some finish work.
